A YouTuber named Cloe Feldman was the first to post it - a very short audio clip that says the same thing two times. Many people are absolutely certain that they hear the word "Laurel" in the audio snippet, but then others are 100% sure it says "Yanny," and neither side can believe that the other hears what they do.

Popular Science got to the bottom of it, recruiting a professor of speech to break down the clip. After analyzing the soundwaves of the audio, he explained that the wave features the characteristics of "L" and "R" sounds, meaning it's probably saying "Laurel." While the waveform of "Yanny" is similar, it isn't the same. Due to some overlaying frequencies from the low quality of the sound clip, some people hear "Yanny."

TMZ caught up with the guy who originally posted the clip, a Reddit user who goes by RolandCamry. He revealed that it is definitely "Laurel," explaining how he recorded the robotic pronunciation of "Laurel" from vocabulary.com off his speakers, which caused the sound distortion. He did it after checking out the site with a friend and arguing over what they heard when they listened to the pronunciation of "Laurel."

But really, how could anyone hear "Yanny" anyways? It clearly says "Laurel."
